Get message statistics for chats
AI agents call beeper_chat_stats to retrieve information from Garza Home MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns statistics about chat messages without modifying, creating, deleting, or executing any operations. It is purely informational. The blast radius of misuse is minimal—an agent could retrieve statistics about message volumes or patterns, but cannot alter messages, delete chats, send communications, or trigger external actions. This is a straightforward Read category tool.
